maximum number of improved features and advantages which make the pinmore useful than previous pins.

in the hair, which has a spring action so that it will grasp the longhairs firmly, which can be readily inserted into the hair without thenecessity of spreading the legs widely apart as in ordinary bobby pinsso that the pin can be easily placed in thedesired position by pushingit lengthwise into place without the need for any substantial separationof the legs, which is invisible to a large extent when it has beenplaced in the hair so that it does not detract from the appearance ofthe coiffure, which has ends formed or shaped in such I a way that theywill readily pass into the body of hair, which is made of such aclass ofmaterial that it can be cheaply manufactured, I

and which can be readily roduced by the use of suitable machines rom thematerial selected for its manufacture.

To these and other ends the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed: I

In the accompanying drawing: Fig.1 is a side elevation on a considerablyenlargedscale of a hairpin embodying my improvements; 1

Fig. 2 is a view similar to Fig. 1' showing the pm as it appears whenthe legs are grasped away from f these recesses or openingsbeinadapted'to receive and retain, hair and 't e. shape of the pin beingsuch as to resist displacement at their extremities and pulled eachother;

Fig. 3 is an edge View of. the pin shown in Figs. 1 and 2;

Figs. 4 .and

5 "are sections, respectively,

on line 4 4 and line 5.5 of Fig. 1; and

Fig. 6 is an end view of the pin looking .to-- ward thefold or butt end.

As shown in the drawing, the improved pin of my invention is for themost part symmetrical in form by reason of the" fact that parts on oneside'of a longitudinal center linehave corresponding parts located onthe opposite side of such line. To an extent, however, the pin isasymmetrical, because the free end portion of one leg is somewhatshorter than the free end portion of theop posite leg, whichrmakesone ofthe legs of the pin somewhat longer than the other. The

' .pin is constructed of relatively inexpensive round wire, but incertain portions of its structure this wire is shaped to form flattenedweb-like portions.

' In the drawing, the short leg of the pin is indicated by referencecharacter 10 and the long leg. by reference character 11. Short.

leglO has a short end portion 12 formed. 551 111181 but longer flattenednd portion 13. The extremities of these en portions are rounded, asshown at 14 in Fi 3, so that they can readily penetrate the air withoutcatching therein. The end portions 12 and 13 are divergent, as shown inFig: 1, and normally occupy the position shown in that View by reason ofthe springiness of the legs. Back of the end portions 12 and 13 the legsare bent to form zigzag portions (these portions being ofroundcross-section) whichpresent a number of projections that are inreglstry with each other. .The projections on leg 10 are indicated at 10in Fig. 2, and the projections on leg 11 are indicated .at

flatteningthe wire, and! leg 11 has a a Q in the hair when the pin hasbeen once positioned. In the rear of the. recess or opening 19 the legs10, 11 are rovided with similar oppositely located we portions or flats20,

. ning able part of their length at the rear of the down the legportions through a noticeortions and in that portion corrugated le gdescribed generall of the pin whic mafy be as the looped or olde tions20, 21 the cross-section of the pin is round or substantially round, asshown at 22, and preferably this ortion 22-;of round cross-section isextended not onl over the extreme butt end of the pin, but to somedegree in advance of this extreme butt end, so that while in theportions 20, 21 the body of the pin is widened through, say, a littlemore than half the distance from the corrugated portion to the extremeinner .end of the pin, the narrow rounded portion is located (118someartly in the longitudinall p y .back

what convergent loop'portlons ocated ofthe' corrugated portions.

By providing the. flattened portions 20 and 21 or their eggmvalents atthe rear of the corrugated shan portions of the pin, the'article isgiven considerable springiness and has an efie'ctive clamping action onthe hair so that the corrugated portions are firmly pressed against thehair from opposite sides by the spring in those portions of the legswhichare disposed toward the'butt. The flat portions 20, 21 are veryeffective in imparting as ring clampm an the leg action to the legportions, portions are so formed as e fectively tb resist longitudinaldislocation in the hair. The sprin I pin is well illustrated in Fig. 2,which showscharacteristic of the the positions taken by the-legs whenthe free extremities thereof are grasped. and 'se rated. It will beobserved that when 's is done the separation of the legs is stronglresisted b the spring portions 20, 21, W11! areonly s 'ghtly displaced(separated) from the osition shown in Fig. 1. Upon release of t e legswhen inthe position shown in 2, they return to the position shown in.Fig. 1 and this will occur when the legs are separated an indefinitenumber of times, owin to the inherent resiliency of the pin iwhich wi lpersist during long periods of use.

The improved pin serves very satisfactorily for use in coifl'ures oflong hair because owing to the formation and disposition of the endortions 12, 13, the pin can be. v ery readily inserted into thefhai'rwithoutga substantial amount of separation'jofthelegs bein necessary.The pin will-be'securely held in the.

hair owing to the 'clampi-ngaction which 7 is providedasjabove'described, and owing to thefformation of the leg p01'tions -Asthe corrugated leg portions areof' round crosssectlon'an'd attenuated,they are to Y a large degreeii-ijiivisibleiwhen the pin isin posit on'inthefcniiiure, and this, of course, isfvery desirable. The butt endportion of the pin is ,also' 'constructed of material hav-' mg'a roundcross-section and this portion (1 portion thereon However, in the rearof the flattened por-- stan'tial portion of their length, and

of the in is likewise-substantially invisible when t e pin is inposition in the hair. Thus the amount of metal which is disclosed to"view when the hair has been'dressed is reduced to a minimum. 7 The pincan be produced from round stock which is comparatively inexpensive andcan be readily made iii quantity by hairpin machines which are notunduly complicated in their construction.

' Various changes can-be made in the details of the structure as hereindescribed without departing from the scope of my invention as defined inthe claims.
